SPECIFICATION forming part of Letters Patent No. 330,124, dated November10,1885.

Application filed August 13, 1885. Serial No. 174,271. (ModeL) To aZZwhom it may concern.-

Be it known that I, HENRY O. J EWELL, a citizen of the United States,residing at the city of \Vashington, in the District of Columbia, haveinvented certain new anduseful Improvements in Flat Rulers; and I dohereby declare that the following is a full, clear, and exactdescription of my invention, which will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, which are made a part of this specification.

Similar letters refer to similar parts in each My invention relates toan improvement in flat rulers.

The object of my invention is to provide a ruler with a soft-rubbercross-piece embedded in the lower face and at each end of therulerplate, to prevent it slipping; also to provide a ruler with ahandle for holding and moving the same,which will facilitate labor andafford more perfect and convenient work, and avoid the soiling of thefingers with ink from the edges of the ruler which come in contact withthe pen.

I attain the object and purpose of my invention by a ruler having thesoft-rubber cross-pieces B B and the handle 0, as illustrated in theannexed drawings, in which- Figure 1 is a top view of my inventioncomplete and in position as used. Fig. 2 is a view of the under side ofmyinvention, show ing the relation and application of the parts whichform the whole.

The ruler plate A is made of wood, metal, or other suitable material forthe purpose, and may be in various lengths and widths to suit the workin which they are to be employed. This ruler-plate A has two or moreholes through its face, through which pass the screws a a, that fastenthe ruler-plate to the handle 0. The number of these screws is governedby the length of the ruler A, which if very long will require a greaternumber of screws than short rulers. The handle 0 may also be fastened tothe ruler A with glue, cement, or their equivalents.

The soft-rubber cross-pieces B B are made in length to correspond withthe width of the lower face of the ruler A, and should be about one-halfinch in width and one-eighth of an inch in thickness. These soft'rubbercrosspieces B B are embedded in the lower face of the ruler A aboutone-sixteenth of an inch in slots made for the purpose at each end ofthe ruler, and are fastened in place with glue or other materialsuitable for the purpose, as shown by Fig. 2.

The handle 0 is made of wood, metal, or other suitable material, and ofa size to fit the hand. The lower end of the handle is provided with along projection to extend along the upper face of the ruler A, by whichit is to be fastened to the ruler, as shown in Fig. 1. The length of theprojections is governed by the requirements of the length of the rulerA, to which it is to be attached.

I also apply the soft-rubber cross-pieces B B to flat rulers withouthandles for the same purpose and in the same manner as shown in Fig. 2.

Having thus described and illustrated my invention, what I claim as myinvention, and what I desire to protect and secure'by Letters Patent, is

A ruler consisting of the ruler-plate A, the soft-rubber cross-pieces BB, and theihandle 0, all substantially as and for the purpose set forthand illustrated.
